Preliminary results from a study of $pi$$sup -$p $Yields$ K$sup -$$K$$sup +$n at 6 GeV/c with the Argonne Effective Mass Spectrometer are presented. The 100,000-event data sample shows a dramatic drop in the Y$sub 4$$sup 0$ moment of the K$sup -$$K$$sup +$ decay angular distribution at a K$sup -$$K$$sup +$ mass of 1500 MeV. This feature is interpreted as a result of f-f' interference, which can also explain the excess of D-wave cross section near 1450 MeV observed previously. (auth)
